What is the difference between Luchang Yantian and Bag Yantian?

Reasons for the formation of Luchang Yantian: The distribution of Yantian is influenced by topography and climate. Luchang Salt Field is located on the west bank of Bohai Bay. Because of this superior natural condition and sun-dried salt: 1. There are long, wide and flat muddy beaches. 2。 Weather conducive to seawater evaporation, this is a short rainy season, and the temperature rises rapidly in spring, and evaporation is vigorous.

Conditions of bag saltworks:

The southwest coast of Taiwan Province Province has flat beaches, gentle terrain, little fresh water injected by rivers, strong monsoon, dry and rainy winter, long sunshine, high temperature, rapid evaporation and high salt content. It has been an excellent saltworks since ancient times. Cloth bags have unique geographical conditions and a long history of drying salt. The history of drying salt in cloth bags can be traced back to the Qing Dynasty, and it has been more than 200 years. The cloth bag began to open salt fields, and Wu Shang, a salt merchant who had been cleaning Daoguang for three years, opened a new salt box, which laid the foundation for the cloth bag drying salt industry; During the Japanese occupation period, the bag salt field became more mature, which made the bag port an important salt port at that time, and sold the bag salt to China and Japan. The glittering saltworks once had the status of "platinum" industry. Like salt fields in other regions, almost all salt workers were replaced by mechanized salt drying, and the bag salt industry declined. There is no sight of drying salt and collecting salt on the huge salt embankment, and the small train that shuttles on the salt embankment has long since retired.
